Depending on your environment, if you are seeing lockouts occurring on a workstation, it will generally be typing a password wrong or saved credentials somewhere. If you are seeing them at a UAG or CAS server, investigate their activesync devices.

At the moment this doesn’t check to make sure there isn’t another device with the same mac address first (so it may not actually create a new device), but this extra validation is a job for another day.

If your organisation is running Lync Server 2013 (or 2010) upon first launch of the Skype for Business client your users will be presented with this:

Restart Skype for BusinessYou have the newer version of Lync called Skype for Business. However, your admin would like you to use Lync or it’s the only version your server supports. Please restart now to use Lync.

I had a report of a user (Bob McUser) turning on their OOF but when people emailed them no auto response was sent. After some basic troubleshooting such as “is the OOF actually turned on?” it was time to dig deeper. Bob had over 100 rules so this is where I focused my attention as Exchange has a rule quota (default: 64KB), and ultimately OOF is a rule.

NB. Don’t install this on Exchange or SharePoint servers – see comment from Chris below

One of the biggest improvements to Windows Server 2012 is the (almost) all encompassing Server Manager. From any 2012 server you can now manage any other 2012 server through WinRM – but if you add a 2008 or 2008 R2 server to Server Manager, you will get a manageability warning of “Online – Verify WinRM 3.0 service is installed, running, and required firewall ports are open“.
